What is the value of Grand Duchy of Lithuania? [opgelost]

   My coin is from between 1508 and 1519. 

          It is in category F of conservation.

 And if so, can you tell me which mint it is? 

                         I couldn't find out.

                                     Thanks.

The year is 1515 (at 11:00-12:00 relative to the rider).

These were struck in Vilnius.

Sigismund The Old minted half groschen only in Vilnius mint.

Three matching your year are for sale in online shops for 20-27 EUR. 53 for sale with asking prices between 13 and 750 euros.

The most common varieties sell for about 10 euro at Polish auction houses, so maybe 15 euro retail.

Yours is not the most common variety (punctuation by 4 dots after LITVANIE), so maybe worth a bit more.   

Thank you Very much.
